Question
Which one of the following is a rich source of
iron?Solution
The correct answer is D
I. x²  – 44x + 468 = 0
II. y²  – 30y + 216 = 0
I. y² - 7 y – 18 = 0
II. x² + 10 x + 16 = 0
I. 10x2 + 33x + 9 = 0
II. 2y2 + 13y + 21 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 34x + 285 = 0
Equation 2: y² - 26y + 165 = 0
I). p2 + 22p + 72 = 0,
II). q2 - 24q + 128 = 0
I). p2 = 81
II). q2 - 9q + 14 = 0
l. 3x2 + 17x + 24 = 0
II. 2y2 + 15y + 27 = 0
If ‘y1’ and ‘y2’ are the roots of quadratic equation 5y2 – 25y + 15 = 0, then find the quadratic equation whose roots are ‘3y1�...
I. 5x + 2y = 31
II. 3x + 7y = 36
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y.
I. x
